APPARATUS FOR CARBURETING AIR.

SPECIFICATION forming part of Letters Patent No. 493,992, dated March21, 1893.

Application filed March 30, 1892. fierial No. 427,100. (No model) To allwhom it may concern.-

Be it known that I, PATRICK I-I. FONTAINE, a citizen of the UnitedStates, residing at Elmo, in the county of Halifax and State ofVirginia, have invented certain new and usef ul Improvements inApparatus for Carbureting Air; and I do hereby declare the following tobe a full, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertains to make and usethe same.

My invention relates to an apparatus for carbureting air for heatingandilluminating purposes, and its object is to greatly simplify theconstruction of such apparatuses, render them more effective and durableand improve the quality of the gas produced; and it consists in certainnovel combinations, constructions and arrangements of parts, as will behereinafter described and pointed out in the claims.

In the drawings, Figure 1 is a vertical central section of my improvedair carbureting apparatus. Fig. 2 is a detail section illustrating theconnection of two carburetor chambers or vessels with the oil reservoirand air forcing apparatus. Fig. 3 is a vertical section of a portion ofthe apparatus showing the auxiliary air holder and compressor modifiedin its construction. Fig. 4 is a plan view of one of the annular staysapplied within the air holder and compressor. Fig. 5 is a'detail of aportion of one of the stays, and Fig. 6 is a horizontal section of thecarburetor chamber, and showing a plan view of the pipe for dischargingthe oil into the chamber.

A in the drawings represents an oil tank having a filling hole withscrew cap E, and an air vent at E, connected by pipe D with an air ventF in a carburetor B. p The carburetor has a lower chamber filled withcharcoal and oil, and an upper chamber supplied with dry charcoal forthe purpose of cleansing the 7 gas as it passes through it.

G is a pipe with a cock at G for conveying oil from tank A to carburetorB; this pipe bends downward, forming a trap at G3 so as to preventpassage of air by said pipe from carburetor B to tank A. This pipe at Hhas many small holes on both sides to cause the oil to flow in manysmall streams upon the charcoal in thelower chamber of carburetor B.

F is an air vent in carburetor B at the level of oil therein, andconnecting with the oil tank at E.

D is aperforated diaphragm upon which the charcoal, saturated with oil,in lower chamber of carburetor, rests.

D is a perforated diaphragm upon which the dry charcoal in upper part ofcarburetor rests.

I is a pipe at bottom of carburetor B with cock for drawing off residuumof oil.

K isa pipe for conveying gas into the house.

M is a pipe for conveying air from air receiver to bottom of carburetor,having one end at L and the other end at O.

Q is a pipe for conveying air from air forcing chamber S to airreceiving chamber S, having one end open at R and the other end closedby check valve P, opening upward. This pipe is considerably larger thanpipe M, so that the air may be discharged from forcing chamber S intoholder or receiving chamber S in a very short time.

S and S are air holders (or air compressors) Working up and down inWater tanks T and T between standards S These air holders aremade'oflight sheet metal, and-have circles of wood at the top and bottomand at each horizontal joint, the said joints being made by lapping thesheet metal over the wooden circles, and driving nails through bothsheets of metal into the wood, then soldering over the joints and nailheads. The wooden circles are made in segments, arranged in two tiers,breaking joints, as shown. These circles might be composed of two halfcircles of wood, steamed and bent like the fellies of a buggy Wheel. Byhaving the circles, or stays of wood, the air holders can be made ofvery light metal, and the horizontal joints can be made more easily bydriving nails through the metal into the wood than by the usual methodof riveting the joints; and at the same time the necessary strength andrigidity for resistance of air pressure be secured.

In Fig. 3, the auxiliary air holder S is shown constructed with a rigidtop and bottom and flexible folding body, instead of being c011-structed of sheet metal as shown in Fig. 1.

The method of operating my apparatus is as follows: The cock G on oiltank is closed and screw cap on filling hole E, is removed. The oil isthen poured into the tank A, the screw cap is tightly closed on E andcock on G opened. The air will then flow from bottom of carburetor Binto the top part of tank A by pipe D, and oil will flow from tank Athrough pipe G, and be discharged in many small streams at H upon thecharcoal in lower chamber of carburetor B. This flow of oil willcontinue until the oil rises in bottom of carburetor B to the top of theair vent F, there by sealing said air vent. The flow of oil will thencease; but when the oil falls below the level of said air vent, by beingchanged into vapor and then carried off by the flow of air through thecarburetor, its flow will be resumed. After the carburetor B has beencharged with oil as described above,the windlass X is turned, winding upcord C and thereby raising the air holder S; valve V on top of said airholder opening downward and admitting air into S; when S is filled withair the Windlass X is released; S then descends forcing the air throughpipeQ into air holder S, thence through pipe M into carburetor B. Thisair is discharged through the lower end of pipe M beneath the perforateddiaphragm D. The air then passesthrough the holesin said diaphragm,being thereby divided into many small streams, and is earbureted bypassing through the oil and oil-saturated charcoal contained in thelower chamber of carburetor B; the carbureted air then passes throughthe dry charcoal contained in the upper chamber of carburetor B, inorder to be deprived of any small globules of oil, and thence by pipe Kdirectly to the burners, or to a gas storage chamber, should such achamher be used. Air holder S is made a little heavier than air holderS, and pipe Q is made considerably larger than pipe M, so that a'greater quantity of air is introduced in holder S by pipe Q than isdischarged in a given time through pipe M, and consequently during thedescent of S, S will be caused to rise, and at the same time air willbeforced through pipe M. After the air in S has been exhausted, the valveP will close, and the flow of air through pipe M into the carburetor Bwill be continued by the descent of S, and the air in S can be renewedby turning Windlass X; thus it will be seen that a continuous supply ofgas can be furnished by this operation. Another reason for having pipe Qconsiderably larger than pipe M is that the air may be discharged from Sinto S in a very short time, so that the operator can charge both S andS with air by remaining at the Windlasssay only about two minutes, andthus it will not be necessary for him to come to the windlass so oftenas it would be if he had to wait a long time for the air to bedischarged from S into S.

What I claim as my invention is l. The combination with a carburetor ofseparate air forcing and air receiving chambers constructed to rise anddescend, and downwardly bowed air pipes of approximate U-shape and ofdifferent diameters for connecting the carburetor and the air forcingand receiving chambers, and conducting air uninterruptedly orcontinuously to the carburetor, the air forcing chamber being providedwith an air admission valve in its top and opening downward, and alsoprovided with a Windlass mechanism for raising and lowering the saidmovable air forcing chamber; and the pipe directly connecting the airforcing and air receiving chambers being of greater diameter than thepipe directly connecting the carburetor with the air receiving chamber,the Whole constructed, arranged and operating, substantially asdescribed.

2. In an apparatus for carbureting air, the combination of a separateoil reservoir A, two or more separate carburetors B, each having aresiduum chamber with a draw 01f cock and a perforated diaphragm at itstop, said chambers being below the oil entrance passage and connected bya pipe; an oil supply pipe G having a U-shaped bend forming a trap G andalso aperforated branch extending from the trap, entering the firstcarburetor, running across the same, connecting with the secondcarburetor and extending across the same, said extension being on aplane above the level of the oil in the residuum chambers; columnsofsaturated char coal below said branch and columns of dry charcoalabove said branch in the carburetor; an air vent pipe D connected withthe reservoirA above the oil therein and with the carburetor B at thelevel of the oil in the residuum chambers, and a system of piping M,connecting the carburetor and extendingfrom the air forcing apparatusand through the carburetor and into the residuum chambers,substantiallyas and for the purpose described.

In testimony whereof I hereunto affix my signature in presence of twoWitnesses.
